Noise Level Results
As I would expect, with the limited voltage supplied during the stock testing, the noise levels of both the TY-100 and the TY-140 were really good - some of the best results we've seen actually.
When I got to adding full power to these fans, I found that while the CFM increases, and you can tell the fan is spinning faster visually, the noise levels don't come up enough to be much of a bother at all.
Considering this is for HTPC environments, I can see why Thermalright chose these fans. For those in a SFF case, likely you are still gaming with a headset on and you can take a bit more fan noise, so the option for better efficiency than what I should is an easy fix for you.
